FRANK L. rUnBUsH, or WnsTFonD, MASSACHUSETTS, AssIGNon To C. G,YsAnerENTs soNs CORPORATION, or GRANITEVILLE, MAssACHUsnTTs, ACORPORATION or MAS- SACHUSETTS CONVEYER Application led `rSeptember'26,1928.v Serial No. 308,418. f

This invention relates to a conveyer for sticky or pasty material,adapted to be used in dri-ers especially.

The principal objects of the invention are to provide the plates orshelves of which the -conveyer is formed in such a form that they can hevery easily removed from the chain without damaging the chains ordisconnecting them and replaced just as easily; to provide the shelvesin a curved form so that .a plurality of them will assume asemi-cylindri-` cal shape where they pass over sprockets so. as toprovide a smooth surface for Contact with a brush or beater to cleanthem off; to provide the shelves or plates of sheet metal havingintegral means for stili'ening the same and avoid hinging them to thechain so that there will be no hinges or equivalent lconstructionA towear out and cause trouble, thus increasing the durability of thisconv-eyer.

Other ohj ects and advantages of the invention will appear hereinafter.t

Reference is to be had to the accompanying drawings in which Figure l isa side view of a conveyer and associated parts constructed in accordancewith this invention; v

Fig. 2 is a plan of a portion of one side thereof;

Fig. 3 is a sectional view looking in the direction of the arrow 3 inFig. 2;

Fig. 4v is a sectional view on the line 4-4 of Fig. 3; and

Fig. 5 is a longitudinal sectional view similar to Fig. 3 but showingthe position of the plates or shelves as they pass over the sprocket.

Conveyers made in accordance with this .invention can he used for manypurposes and for conveying many materials but particular advantage isobtained in the conveying of sticky and pasty material which would beapt to stay on conveyer shelves as they pass over the sprockets at thedelivery end, the same being combined with means forengaging thematerial there and removing it.`

nThe conveyervis shown pairs of sprocket wheels l0 which support linkchains 11, one on each side. The chains are shown as double and providedwith loose wheels 9 which engage in depressions 8 in the bases ofthesprocket wheels and constitute the sprocket connection for driving thechains. rlhe links are curved to the same .curvature as the sprocketwheels. Each link is provided with two pins l2 projecting inwardly andthe plates orvshelvesrl3 are supported thereby, the pins passing intoperforations 14 in angle irons l5 riveted to the bottom of each shelf atopposite ends. j f

The object of this construction, these pins constituting the solesupport for the shelves 13, is that at a distance from the sprocketthechains can he separated enough to pull the pins out of the perforations14 and thus remove the shelves and replace themk in case of any damage,for the purpose of renewing the conveyer or anyof the shelves'thereon.

It will henoticed that these shelves 13 are of convex form and theyIconstitute in each case a part of the arcof a circle of the sizeof thepitch diameter of the sprockets 10. This is .for thepurpose ofcausing'the conveyer to assume a smooth semi-cylindrical form whenpassing over the sprockets for a purpose that will appear. ,Y n

These shelves are formed of sheet metal and each is provided with anintegral right angu lar projectionl 16 extending inwardly whichprojections are in radial positionwith respect to the arc of the curveof the shelf. These projections come in Contact with each other in theposition shown in Fig. 5-where they pass over the sprocket. Theprincipal object of these projections, however, is to stiien each ofthese shelves so that they may hemade of comparatively thin sheet metaland still have considerablestrength.

The reason for the formation of the plates'y as supported on twoV inacurved form as stated, so thatthey will l have a Icontinuous smoothsurface where they A stick to it .of theV arrowin veyer are allowedto'passfunde'r the beater and'k brush without being operated uponby-'jy. them.

` of the drierrin which the conveyer is adapted y thereinby any personskilled out departingfroni the scope shelves pass over' sprocketspresents from a short distance at points between the pivot pins, of aset of shelves, each having an angle iron at each end underneathprovided with the same number of perforations in a vertical part of thesame for detachably receiving said pins so that the chains' can bedetached from the angle irons by moving them away from them laterally,without disassembling the chains.

In testimony whereof I have hereuntoafliked mysignaturel Y FRANK FURBUSHto beV used, which 1s provided with a weight 23V and adjusting screw 24:comingagainst :a 1

' AlthoughIhave Villustrated and described onlyone form of theinvention, I amV aware ofV the fact. that' modifications can be made intheart withi y of the vinvention as expressed in the'claims. Therefore,I do noty wish to be limited in this respect,but "What'I do claim is:- l

2. In a conveyer,'the combination with a pair of chains, the linksthereof having pivot pins at their ends `by which they are pivoted`together, each link of each chain havinga pluralityy of pinsfprojectinginwardly therea smoothv surface which is the sprocket Wheels for the yvse
